SPECIFICATION forming part of Letters Patent No. 755,245, dated March 22, 1904.

Application filed fuly 14, 1903.

T @ZZ whom/ it noa/y concern.'

Be it known that I, OLAF LEONHARD AUGUS- TINUs RIEGELs, engineer, a citizen of the Kingtion with the oil and the steam supply.

The invention has for its object to provide a preferable construction and arrangement of the said chamber, so that the entire amount of oil carried in by the chamber is linely scattered in the steam.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation, partly in section, of my improved lubricator in one form of embodiment. Fig. 2 is a detail sectional view drawn to an enlarged scale. Fig. 3 is a part of the section along the linea Z; in Fig. 2. Fig. L1 is an enlarged detail view, partly in section, of the feeding-rod. Fig. 5 is adiagrammatical view of a double-acting form of the invention.

The most important part of the lubricator is the feeding-rod 1, rwith the chamber 2. This rod passes from the atmosphere through a stuffing-box 3, then directly through the oilsupply L1, and finally through a stuii'ing-box 5 into that part 6 which carries the steam to the cylinder. The part 6 is here shown as being a pipe; but it may be either the steamsupply pipe leading the steam from the boiler to the steam-chest, the steam=chest itself, the throttle-valve, or,in generahanypart in which the oil is to be scattered within the steam. This part 6 carries a clamping device having on one side a threaded opening, into which the threaded stud 16 of the lubricator is screwed.

The feeding-rod 1 is by means of any suitable part of the machine either directly or indirectly, as shown, given ato-and-fro motion in such a manner that the chamber 2 is brought alternately in connection with the oil-supply Serial lo-(165,523. (No model.)

away by the steam flow and scattered in the same. In order that the oil readily and surely shall be carried away, the chamber 2- at the end opening in the direction of the steam flow is narrowed, as indicated at 9, Fig. 2. The result of this is that the oil which by the steam is forced out through the narrow opening 9 will be scattered or spread with a great velocity in the iowing steam. VIt is not, however, preferable to arrange the longitudinal direction of the chamber 2 9 at right angles to 65 the axis of the feeding-rod 1, as then a drop of the oil remains adhering at 10 to the inner surface of the pipe 6 after the chamber has been withdrawn therefrom. If the chamber 2 is, on the contrary, arranged inclined-for 70 instance, at forty-five degrees to the axis-the above-named inconvenience will be entirely` avoided. In the drawing Fig. 1 the chamber 2 is shown as being arranged at forty-five degrees both to the aXis of the rod 1 and to 75 the iowing direction of the steam. This last arrangement or equal inclinations from both directionsis employed only for practical purposes, as thereby the lubricator may be turned ninetygdegrees in order to be arranged and to 8O have the'motion impartedin the manner which is the most suitable for the several cases.

In Figs. 1 and 2 the part 7, forming part of the oil-supply A, carries the stuffing-,box 5, and

at its end it has an extension 16, fitting into the 8 5 pipe 6. This part 7 is provided with a projecting arm 18, in which is formed a bearing or carried a pin fora ratchet-wheel 11 and for a pivoted lever 12, having, a spring-actuated pawl 13 in engagement with said ratchet- 9o wheel. This latter is, by means of a crank-pin 15 and a link 14., connected with the feedingrod 1, so that the rod has imparted to it a toand-fro motion when the ratchet-wheel is rotated under influence of the oscillating lever 12. The lever 12 is given the oscillating motion in any suitable manner from any movable part of the machine.

In Fig. 5 is shown diagrammatically a double-acting lubricator.

Here the two rods 1 10o are combined with a double-armed lever 21, operated by an arm 22.

When the feeding-rod 1 passes from the oil-supply 4 directly through a stuffing-box 5 into the steam-supply 6, the chamber 2, being withdrawn, will carry with it a small amount of steam under high pressure into the oil-supply 11. This steam will distribute itself in the oil, partly causing the oil to foam and partly collecting itself in the form of water at the bottom of the vessel 1, from which it from time to time must be removed. In order to prevent this inconvenience, two rings 17 and 19 are introduced within the stuing-box 5, dividing this latter into three parts. The ring 17 has an inner segmental groove 20, which through a hole 23 and an outer cross-recess 24 is in connection with an inner longitudinal groove 25 in the stufIing-box 5, which groove 25 finally is connected with the atmosphere through a hole 26. Between the adjacent ends of the rings 17 and 19 is arranged a packing, and the ring 19 has an inner segmental groove 27 similar to the groove 20.

lhen the chamber 2 9 is within the steamsupply 6, the oil is scattered in the steam and the chamber filled with steam of high pressure. The chamber then moves back through the inner end of the stuing-box 5, and coming just beneath the groove 20 the chamber 2 thereby is brought in connection with the atmosphere, whereby the steam will run out through the passage 26. The chamber then moves farther outward, passing' the groove 27 and passing through the outer end of the stufIing-box 5 into the oil-supply 4 in order to be refilled with oil. IVhen the chamber further on again moves inward toward the steamsupply, the oil first is gradually heated to approximately the temperature of the steam, because the inner end of the feeding-rod 1 has nearly this temperature. During this heating the oil in the chamber 2 9 will expand, so as to leave a drop in the groove 2O when passing the same. This is prevented by use of the groove 27. The oil has already reached the said temperature when the chamber during its movement to the right has arrived at the groove 27, where the said dropisleft, and this drop is again removed from the groove 27 when the chamber during its movement to the left is passing beneath the groove 27, whereas no oil will be left in the groove 20.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ina lubricator, the combination of an oilreservoir, a feeding-rod passing through said reservoir and into a steam carrying part, means for moving the rod to and fro, and a chamber 2 in said rod arranged in an inclined direction to the rod-axis and open to one side of the rod only, a smaller chamber 9 open to the other side of the rod and being connected with the chamber 2 and which chambers during the movement of the rod feed oil from the oil-reservoir to the steam-carrying part.

2. In a lubricator, the combination of an oilreservoir, two feed-rods passing through said reservoir and into a steam-carrying part, a double-armed lever 21 connected with said rods in order to move them alternately to and fro, an oscillating arm 22 operating the lever 21, and a chamber 2 in each rod, said chambers being arranged in an inclined direction to said rods and feeding alternately oil from the oilreservoir to the steam-carrying part.

3. In a lubricator, the combination of an oilreservoir, a feeding-rod passing through said reservoir and through a stufiing-box into a steam-carrying part, a stuffing-box 5, a ring 17 introduced into said stuiing-box and having an internal segmental groove 20 and passages in said ring and the wall of the stufiingbox connecting said groove with the atmosphere, and a chamber 2 in said rod arranged in an inclined direction to the rod-axis and which chamber during the movement of the rod feeds oil from the oil-reservoir to the steam-carrying part.

4. In a lubricator, the combination of an oilreservoir, a feeding-rod passing through said reservoir and through a stuffing-box into a steam-carrying part, a stuiiing-box 5, a ring 17 introduced in said stuihng-box and having an internal segmental groove 2O and passages in said ring and the wall of the stuffing-box connecting said groove with the atmosphere, a ring 19 introduced in the stuffing-box 5 and provided with an internal segmental groove 27 and pressed against the ring 17 with intermediate packing, and a chamber 2 in said rod arranged in an inclined direction to the rodaxis and which chamber during the movement of the rod feeds oil from the oil-reservoir to the steam-carrying part.

5. In a lubricator, the combination of an oilreservoir, a feeding-rod 1 passing through said reservoir and into a steam-carrying part, means for moving the rod to and fro, and a chamber 2 in said rod, said chamber being, at the end which opens in the direction of the steam iow, narrowed at 9, and being arranged in an inclined direction to the rod-axis and which chamber during the movement of the rod feeds oil from the oilreservoir to the steam-carrying part.

In testimony whereof I have hereunto affixed my signature, this 25th day of June, 1903, in the presence of two witnesses.
